Matt from SRS here. Glad I could help, earlier on the phone. The foucusing square can be used on EM-5,EP-5,EPL-5 and EPM-2. The size is adjusted in the touch
screen menu (from 5 to 14x can be selected, bigger the number the smaller the foucus square is) and I have assigned this to a function button for easier use when taking pictures of aviation or wildlife. (I use the EM-5 with the 75-300mm lens for this). I also use this for macro work as it makes focusing much more accurate and quicker. Hope this helps, i'll try and pop on here as much as I can to help. Happy shooting to everyone, and don't let people tell you that it can't be done on an Olympus camera, it CAN!!
